Figure 36 shows a generation of a pulse with a pulse delay of four and a
pulse width of three (using the rising edge of Source).

Retriggerable Single Pulse Generation
The counter can output a single pulse in response to each pulse on a
hardware Start Trigger signal. The pulses appear on the Counter n Internal
Output signal of the counter.
You can route the Start Trigger signal to the Gate input of the counter. You
can specify a delay from the Start Trigger to the beginning of each pulse.
You also can specify the pulse width. The delay and pulse width are
measured in terms of a number of active edges of the Source input.
The counter ignores the Gate input while a pulse generation is in progress.
After the pulse generation is finished, the counter waits for another Start
Trigger signal to begin another pulse generation.
Figure 37 shows a generation of two pulses with a pulse delay of five and a
pulse width of three (using the rising edge of Source).
